Latest Patents

Lacey holds a patent for a CMOS tapered gate and synthesis method. This invention augments a high-performance gate library with tapered gates. The design varies the widths of the stacked devices to reduce delay through some of the input pins. For instance, in a tapered NAND gate, the bottom devices in the NFET stack have longer widths than the top device. This configuration achieves a smaller top input to output pin delay, albeit at the expense of a larger bottom input to output pin delay. The synthesis algorithms employed modify the input net to gate pin connections and replace traditional non-tapered gates with tapered gates. This modification improves the delay of timing-critical paths by swapping the latest arriving gate input net with the net connected to the top pin. The gate is then converted to a tapered gate, provided the paths through the bottom gate input(s) are not timing critical.
